Electronic device and lock device for locking module of electronic device

Abstract

An electronic device and a lock device for locking the module of the electronic device are disclosed. The electronic device includes a module, a connection interface, a plug, and a chassis. The module is movably disposed on the chassis. The connection interface is disposed on the chassis and is electrically coupled to the module. The lock device includes a lock part, an elastic unit, and a contact part. The lock device is movably disposed on the chassis. When the plug is not in connection with the connection interface, the lock part locks the module. The elastic unit provides a predetermined force to affix the module. When the plug connects the connection interface, the plug pushes the contact part of the lock device for moving a predetermined distance to release the module.

1. A lock device within an electronic device, the electronic device including a chassis, a module movably disposed on the chassis at a home position, the module having a block extended outwardly toward the chassis and a connection socket to be disposed on the chassis near to the home position, the connection socket selectively connecting to a plug of an external electronic device, the lock device comprising:
 a hook part movably disposed on the one end of the lock device for engaging with the block; 
 an elastic unit, one end of the elastic unit connecting to the chassis and providing a predetermined force to affix the module at the home position; and 
 a contact part protruding from the other end of the lock device and interfering with a connection between the connection socket and the plug when the module is in the home position, wherein the plug pushes the contact part to overcome the predetermined force, when the plug connects to the connection socket, making the lock part release the module. 
 
   
   
     2. The lock device of  claim 1 , wherein the plug further comprises a transmission cable for communication with the external electronic device, and wherein the connection socket is electrically coupled to the plug when the plug connects to the connection socket, and the module communicates with the external electronic device through the connection socket and the transmission cable. 
   
   
     3. The lock device of  claim 1 , further comprising an axle, and the lock device is rotatably disposed on the chassis by means of the axle. 
   
   
     4. The lock device of  claim 1 , wherein the elastic unit is a spring. 
   
   
     5. The lock device of  claim 1 , wherein the lock device comprises a magnetic unit providing a force to affix the lock device. 
   
   
     6. The lock device of  claim 1 , wherein the connection socket comprises a Universal Serial Bus (USB) socket. 
   
   
     7. An electronic device selectively connecting to a plug of an external electronic device, the electronic device comprising:
 a chassis; 
 a module movably disposed on the chassis at a home position, the module having a block extended outwardly toward the chassis; 
 a connection socket connected to the module and to be disposed on the chassis near to the home position of the module; and 
 a lock device movably disposed on the chassis, the lock device comprising a hook part, an elastic unit, and a contact part, wherein the hook part is movably engaged with the block on the chassis, one end of the elastic unit connects to the chassis and provides a predetermined force to affix the module at the home position, and the contact part protrudes from the lock device at the one end and opposite to the hook part and interfering with a connection between the connection socket and the plug when the module is in the home position; 
 and wherein the plug pushes the contact part to overcome the predetermined force, when the plug connects to the connection socket, making the lock part to release the module. 
 
   
   
     8. The electronic device of  claim 7 , wherein the plug further comprises a transmission cable for communicating with the external electronic device, and the connection socket is electrically coupled to the plug, when the plug connects to the connection socket, and the module communicates with the external electronic device through the connection socket and the transmission cable. 
   
   
     9. The electronic device of  claim 7 , further comprising an axle, and the lock device is rotatably disposed on the chassis by means of the axle. 
   
   
     10. The electronic device of  claim 7 , further comprising an elastic unit providing a force to affix the lock device. 
   
   
     11. The electronic device of  claim 7 , wherein the lock device further comprises a magnetic unit providing a force to affix the lock device. 
   
   
     12. The electronic device of  claim 7 , wherein the electronic device is a scanner and the module further comprises an optical image capture unit. 
   
   
     13. The electronic device of  claim 7 , wherein the connection socket comprises a Universal Serial Bus (USB) socket, and the plug comprises a Universal Serial Bus connector, and wherein the module is electrically coupled to the USB connector through the USB socket when the USB socket connects to the USB connector.
